The producers behind Napoleon Dynamite are suing Fox movie bosses over allegations they’re owed millions in royalties. Bosses at Napoleon Pictures have filed suit against executives at Fox Searchlight Pictures, the independent division of 20th Century Fox, claiming they’ve been cheated out of home video revenue and TV licensing fees for the 2004 cult comedy.

The film, starring Jon Heder as a hapless high school student, grossed nearly $45 million at the box office and went on to become a top-selling home video.

The lawsuit, filed on Tuesday in Los Angeles and obtained by the Hollywood Reporter, is seeking $10 million for breach of contract and negligent misrepresentation with respect to other income from the film.
